<< You are correct in assuming the misconception on your part was the key

 sphere { <0,0,0>, 1 = a sphere "2" units across !!!

Yes I understand this Ken.  But is not a sphere, sphere{<0,0,0>,5} centered
by default at the origin?  So, it extends, 5 units up, 5 down, 5 left, 5
right, 5 in, 5 out.  it is completely centered.  Thus; by making a sphere
radius 2.5 (diameter 5) by translating it by it's radius to the right, the
left edge should be at the origin, and the right edge should be at 5,0,0
correct?  In this image it does not appear that way.
